DESCRIPTION

The invention relates to a power window unit. The prior art includeselectrically powered power window units for raising and lowering thewindows of a motor vehicle; these electrically powered power windowunits are suitable for installation in the doors of motor vehicles andhave either an electric motor connected to a transmission or a gearedmotor as the drive unit, which can be connected to the motor vehiclebattery via a switch.

The window, which is mounted in the vehicle door and can be raised orlowered by an electrically powered power window unit, is fastened at itslower edge to a guide carriage slide which can be moved up or down alonga profiled rail by means of an closed cable loop, for example. The cableloop goes around a cable drum, which can, for example, be driven by aworm gear transmission by the electric motor in a compact drive unit,which includes the cable drum in addition to the worm gear transmissionand the electric motor and is fastened to the supporting surfaces on theinside of the vehicle door or a base plate as well as to the profiledrail.

As an alternative, the drive unit can be used to operate a cross armwindow lifter.

Because different forces are necessary to raise and lower the window,the drive unit has an electronic control and regulating system, which isconnected to an operating switch, and can also be equipped with a speedsensor. Depending on the position and way the operating switch is used,the window is completely raised, completely lowered or held in a desiredintermediate position, whereby the electronic control and regulatingsystem ensures a smooth raising or lowering procedure.

A configuration of the prior art for an electrically powered powerwindow unit and an electronic control and regulating system in a motorvehicle door is schematically illustrated in FIG. 1.

The drive unit for this configuration of the prior art consists of ageared motor 2 with an electric motor 21 and a connected transmission22, which is connected by means not shown here to the cable loop forraising and lowering the window. The rotor shaft 23 is mechanicallycoupled to a speed sensor 3, which is connected via a conducting cableto the electronic control and regulating system 4 located in a separatehousing. The electronic control and regulating system 4 is connected tothe power supply of the electric motor 21 via a line 41 and a plug-incontact 24. A line 42 leads to the operating switch in the interior ofthe vehicle via a plug connector as well as to the motor vehicle battery45 via a line 44.

As seen in the configuration diagrammed schematically in FIG. 1, thedrive unit 2 and the electronic control and regulating system 4 are inseparate housings, which must be essentially impervious to moisture;i.e. water vapor which develops must be able to leave the system whileliquid. Rain water in particular must not be able to enter through themembrane. Between the separate housings, several cable connections arenecessary, for the power supply of the electric motor 21, and for speedmeasurement for the connection between speed sensor 3 and the electroniccontrol and regulating system 4. The plug-in contacts 24, 43, like thehousing to hold the drive unit 2 and the electronic control andregulating system 4 must be impervious to moisture in order to preventshort circuits.

The separate placement of the drive unit 2 and the electronic regulatingsystem 4 thus requires high assembly costs and substantial expendituresfor cable connections between the two housings as well as theconfiguration of moisture tight plugs and jacks. There is a risk thatmistakes will be made during establishment of the cable connectionsbetween the two housings which results in high overall costs for theinstallation of the electrically powered power window unit.

An additional problem is that the cables 40, 41, 42 between the separatehousings to hold the electronic control and regulating system on onehand and the drive unit on the other hand in the vehicle door move whenthere is a high degree of moisture, thus requiring complex and expensiveseals.

Finally, the subsequent mounting of the housing in the vehicle doorrequires a large amount of work because two separate mounting proceduresmust be performed; i.e. there must be separate attachment brackets forfastening to the door wall and an appropriate fastening means.

An additional disadvantage of the prior art is that the speed sensormust be separately mounted on the housing of the drive unit.

DE-GM 87 12 863.2 discloses an electrical machine, consisting of ahousing, a front-side end plate and a terminal box, which terminal boxhas a terminal strip, cable lead openings and a terminal cover with agasket. In order to minimize the width of the electrical machine and tosimplify fabrication, the terminal box of an electrical machine of theprior art is integrated into one of the front-side end plates of theelectric machine. As a result, the terminal box has a cavity under thecladding of the shell of the end plate, with an outward-leading hole inthe end plate, which is releasably closed by the terminal box.

The terminal cover of the device of the prior art is a rectangular plateand a gasket is integrally connected to the terminal cover. In addition,the terminal strip is integrally connected to the terminal cover and hasconnecting jacks or pins which can be connected to the cable-sideterminal shoes. The cable lead openings are made in the shell of the endplate.

With this device of the prior art, the terminal box is an integralcomponent of the front-side end plate of the electrical machine;however, because of the defined configuration of the terminal box in thefront-side end plate, however, a fixed correspondence between theterminal box and the electrical machine is specified, which does notpermit a variable configuration of the terminal box and thus of theelectronic control system.

The object of the current invention is to create an electrically poweredpower window unit of the generic type described above, which results inlow component and installation costs by eliminating installation errors,guarantees great resistance to moisture without complex and expensiveseals and makes possible modular construction, whereby a drive unit canbe connected to various, easily accessible and interchangeableelectronic control and regulating systems for various motor vehicletypes and models.

This object is achieved by the characteristic feature of claim 1.

The solution according to the invention guarantees low component andinstallation costs by eliminating installation errors, because noadditional wiring is needed between the drive unit and the electroniccontrol and regulating system. By locating all parts in a common,moisture tight housing, no additional costs for seals are necessary andinexpensive plug connectors can be used because they are locatedexclusively in a water-tight chamber.

An advantageous refinement of the invention is characterized by the factthat the electronic control and regulating system are located on acircuit board which can be inserted or plugged into a terminal of thecommon housing, whereby the circuit board can be connected to a plug-inmodule which can be plugged into an opening in the connector of thecommon housing and has plug contacts, which can be connected tocorresponding mating plug contacts of the drive unit and whereby theplug-in module has an exterior surface which is tight up against thecommon module.

The modular structure makes possible the use of a specified drive unitfor various motor vehicle types and for various embodiments, wherebyadaptation to the respective motor vehicle type and type of operation isdetermined by means of the electronic control system. In this manner,various electronic circuits, such as jamming protection circuits,electronic circuits for control of the raising and lowering of thewindow and circuits for the control of the windows in association with acentral locking system can be used. Guide elements in the housingopening and plug-in module make possible rapid, safe installation,whereby the contact between the electronic control and regulating systemand the drive unit is established during insertion, which, on the onehand, guarantees correct polarity and, on the other hand, saves asignificant amount of time during installation.

In an alternative embodiment, the circuit board can be inserted into thelockable interior of the connector of the common housing by means of acover and connected to the mating contacts of the drive unit by means ofa contact device.

As an alternative to this, the circuit board can be connected directlyto the cover of the common housing and connected to the mating contactsof the drive unit via a contact device. In this embodiment as well,modular design enables the use of various circuit board configurationsfor various motor vehicle types and embodiments, whereby adaptation tothe respective motor vehicle type and type of operation is accomplishedvia the electronic control system of the circuit board. This ensures acompact design and easy access to the terminal. The desired controlfunction can be realized by installation of the appropriate circuitboard.

The alternative connection of the circuit board to the cover makespossible a simple, clear, and space saving configuration.

Analogous to the placement of the electronic control system on a plug-inmodule, fast, sure installation can be ensured by means of guideelements in the interior of the connector when the electronic controland regulating system is located on a circuit board, whereby theconnection between the electronic control and regulating system to thedrive unit is made by insertion of the contact device of the circuitboard into the corresponding mating contacts of the drive unit, which,on the one hand, guarantees correct polarity and, on the other hand,guarantees a minimal expenditure of time during installation.

An advantageous embodiment of the invention is characterized by the factthat the plug-in module has a receptacle of the speed sensor, which,when the plug-in module is inserted into the common housing, contactsthat transmitter part of the speed sensor which is connected to therotor shaft of the geared motor or is located across from, but not incontact with, the transmitter part of the speed sensor.

This refinement of the invention simplifies speed measurement andeliminates the need for the separate mounting of the speed sensor andits connection to the electronic control and regulating system. Thespeed can then be measured with or without a wall between the drive unitand the part of the common housing holding the electronic control andregulating system.

An advantageous refinement of the invention is characterized by the factthat the plug-in module consists of a plug-in element containing theelectronic control and regulating system, which element is connected onone hand to the outer surface oriented perpendicular to the plug-inelement, and which has a plug element opposite the outer surface, whichcontains the receiver part of the speed sensor and the plug contacts,whereby a power and signal bushing connecting the electronic control andregulating system to a motor vehicle battery and a control switch islocated in the outer surface and whereby a gasket is inserted in agroove running on the outer surface around the circumference or a groovein a shoulder of the outer surface.

This refinement eliminates the need for the connection of a cableharness to the drive unit or to the geared motor and, on the other hand,provides a satisfactory contact for the power supply of the drive unit.Furthermore, this embodiment makes possible a speed measurement systemwhich does not suffer from any of the contact and connection problemswhich can adversely affect proper measurement of speed.

An advantageous configuration of the invention is characterized by thefact that the plug element has a front-mounted, center-stop or lug forthe calibration of the receiver parts of the speed sensor, which arelocated on both sides of the stop surface and the plug contacts adjacentto the stop surface. Because of this, the speed sensor can consist of aHall sensor, a photoelectric or an inductive sensor as desired.

This configuration guarantees a defined position of the speed sensor andcreates the conditions required for contact-free speed measurement.Furthermore, this embodiment of the invention requires a minimal amountof space, resulting in an extremely compact unit overall.

An additional advantageous embodiment of the invention is characterizedby the fact that the upper and lower sides of the plug-in element havelugs or tabs which are offset diagonally from one another and which areguided in corresponding guide grooves in a common housing.

The diagonally offset orientation of guide elements on the upper andlower sides of the plug-in element in association with correspondingguide grooves in the common housing facilitate installation and alsoguarantee a defined location of the plug-in module in the commonhousing. Furthermore, the guide elements can be used for codingpurposes; i.e., a specific layout of the guide elements can be used toensure the correspondence of specified plug-in modules to the commonhousing, which prevents the erroneous connection of incompatibleelectronic control and regulating systems to the drive unit in question.

Finally, an additional advantageous configuration of the invention ischaracterized by the fact that all of the sealing surfaces areconstructed using to two-component technology. Thus, the two-componenttechnology can be employed as early as the injection molding of theindividual element, and the application of rubber gaskets is no longernecessary.

The idea upon which the invention is based is explained more closely onthe basis of the embodiment illustrated in the accompanying drawings.

FIG. 1 shows a schematic representation of a configuration of the priorart of an electrically powered power window unit in a motor vehicledoor.

FIG. 2 shows a schematic representation of the assembly according to theinvention of an electrically powered power window unit with a separaterepresentation of the plug-in module.

FIG. 3 shows an end view of the plug-in module.

FIG. 4 shows a plan view of the plug-in module.

FIG. 5 shows a plan view of the drive unit of an electrically poweredpower window unit with the connector of an assembly oriented at rightangles to the drive unit.

FIG. 6 shows a side view with a partial cross section through theassembly along the Line A--A of FIG. 5.

FIG. 2 shows the integrated assembly in a common housing 1 consisting ofa drive unit 21 and 22 as well as a plug-in module 5, which contains theelectronic control and regulating system 4 as well as the contact devicefor the power supply of the drive unit and parts of the speed sensor.

As shown in FIG. 2, the plug-in module 5 can be installed completelywithin the common housing 1 of the assembly and, when installed, isenclosed moisture tight. The plug-in module 5 is inserted into theinsertion point in the common housing 1 until it rests against a stopformed by a rib 100. When installed, the exterior wall of the plug-inmodule 5 forms a firm, moisture tight seal with the common housing 1, sothat parts of the assembly inside the common housing 1 are not exposedto any moisture, yet water vapor formed inside can be discharged throughthe membrane at any time.

In a separate representation, FIG. 2 also shows the structure of aplug-in module 5 which can be inserted in the direction of the twoarrows into the insertion point in the common housing 1.

The plug-in module 5 consists of a plug-in element 6, on which theelectronic control and regulating system 4, including a micro-computer40, are mounted. The micro-computer 40 can be programmed as desired,depending on the motor vehicle type in which it is installed.Perpendicular to the plug-in element 6, one exterior wall 8 is connectedto the plug-in element 6 on one end, which exterior wall 8, when theplug-in module 5 is installed, forms the outer closure of the plug-inmodule 5 and is flush with the housing outer wall of the common housing1.

There is a gasket 9 in a shoulder encircling the exterior wall 8 which,when the plug-in module 5 is installed, forms a moisture tight sealwhich prevents the penetration of water into the interior of the commonhousing 1. In the exterior wall 8, there is either a moisture tightcable bushing 10, or a corresponding power or signal plug connectionwhich represents the connection to the control switch as well as to thepower supply of the assembly shown in FIG. 2.

On the opposite end of the plug-in element 6 is an elongated plugelement 7, which, in the embodiment illustrated, is an extension of theupper side in the area of the upper side of the plug-in module 5. Theplug element 7, the configuration of which is shown in more detail inFIGS. 3 and 4 described below, contains on one hand the plug contacts11, 12 for the power supply of the drive unit, and on the other hand thereceiver parts 31, 32 parts of the speed sensor.

To install the electrically powered power window unit assembly withintegrated electronic control and regulating system and speed sensor, itis only necessary to insert the plug-in module 5 in the direction of thearrow into the respective opening in the common housing 1 until contactis made with a stop or lug, whereby in this position, the exteriorsurface 8 of the plug-in module 5 forms a flush closure with theexterior wall of the common housing 1. In this position, contact is alsomade with the power supply of the drive unit 2, which is located in thecommon housing 1, as well as a connection between the speed sensorreceiver parts 31, 32 located in the plug-in module and the speed sensortransmitter part 30, which is connected to the rotor shaft 23, so thatprecise speed measurement is guaranteed. This speed measurement ispreferably accomplished by means of a contact-free Hall sensor or aphoto-electric or inductive measuring device.

FIG. 3 shows an end view of the plug-in module 5, while FIG. 4 shows aplan view of the plug-in module 5.

The plug element 7 on the front side of the plug-in module 5 contains acentral stop or lug for the calibration of two Hall sensors 31, 32,which are located on both sides of a rib 100. They are located on abeveled surface 73, 74, and partly surround the transmitter part 30 ofthe speed sensor for an improved electro-magnetic connection.

Between the Hall sensors 31, 32, which form the receiver part of thespeed sensor, and the rib 100 for the calibration of the Hall sensors31, 32, there is one positive and one negative plug contact 11, 12,which, when the plug-in module is fully inserted, can be connected torespective mating contacts, which are connected to the power supply ofthe drive unit.

In the illustrated embodiment, the plug contacts 11, 12 are designed astip jacks, into which corresponding projecting plug contacts of thedrive unit can be plugged. Of course, the plug contacts 11, 12 on theplug-in module 5 can also be designed as plugs, which can be pluggedinto the corresponding receptacles of the drive unit.

There are guide tabs 61, 62 oriented diagonally to one another on theupper and lower sides of the plug-in element 6, which slide into thecorresponding guide grooves in the housing opening of the common housing1 and thus make possible safe and correct insertion of the plug-inmodule 5 into the housing opening. By means of the guide tabs, tiltingof the plug-in module 5 during insertion is prevented and a drawereffect is thus created; however, the guide tabs 61, 62 can also be usedfor coding of the plug-in module 5, so that a micro-computer programmedin a specified way can only be used for a specified drive unit.

FIG. 5 shows a plan view of a variant of the invention with a connector26 of the common housing 1 offset at an angle from the drive unit 21,22.

In this embodiment, the circuit board which holds the electronic controland regulating system 4 is not inserted into the common housing from anend of the connector, but is inserted into the connector 26 through thetop or bottom. A cover 27 which covers the connector 26 can either beopened on a hinge, lifted off or moved horizontally, so that theinterior of the connector 26 is free to accept the circuit board 6.

As an alternative to this, the circuit board 6 can be directly fastenedto the inner surface of the cover 27, which results in a space-savingdesign which is easy to inspect.

Not shown in greater detail are mating contacts in the connector 26which are used to establish a connection to a contact device 70 havingseveral connecting pins, which are connected to the electronic controland regulating system 4 of the circuit board 6.

After the contact device 70 has been connected to the mating plugcontacts, the connector 26 is re-closed, whereby a power and signalbushing 10 connected to the circuit board 6 projects beyond the frontwall of the connector 26 when the connector 26 of the common housing 1is closed, so that the electrical connection to the circuit board 6 canbe established via a cable harness.

FIG. 6, a side view with a partial cross section along the line A--Aaccording to FIG. 5, clearly shows the correspondence between the driveunit 21, 22 and the connector 26 of the common housing 1 and thelocation of the circuit board 6 in the connector 26, as well as thepower and signal bushing 10 in relation to the location of the circuitboard 6 in the connector 26.

The enclosed, compact design of the assembly is apparent in thepreceding description of an embodiment of the electrically powered powerwindow unit according to the invention. In addition to the significantlyeasier installation and reduction of the connecting elements of theindividual assembly parts, absolute moisture tightness is achieved andthe possibility of connection errors eliminated. At the same time, speedmeasurement for control of the drive unit during raising and lowering ofthe window is significantly facilitated and errors during measurement ofcurrent speed values are eliminated.

Inexpensive plugs can be used as the plug elements still necessary,since they are located in a completely water tight chamber, whicheliminates corrosion problems.

Finally, due to the modular design, all sorts of electronic devices canbe located on the plug-in module, so that jamming protection circuits orregulating circuits for raising or lowering of the window, as well as acombination of window controls with a central locking system ispossible.

The embodiments of the invention are not restricted to the preferredembodiments described above. Rather, a number of variants areconceivable, which utilize elements of the described invention even withessentially different embodiments.
